In order to shield Blurred Lines, the hottest hit of the summer, Robin Thicke, Pharrell Williams and Clifford Harris, Jr. are going to court.

A lawsuit was filed Thursday in California federal court by the trio against Marvin Gaye's family and Bridgeport Music, which owns some of Funkadelic's compositions. At issue are complaints about similarities between Blurred Lines and at least two songs.

According to the suit, a copy of which was obtained by The Hollywood Reporter, "Plaintiffs, who have the utmost respect for and admiration of Marvin Gaye, Funkadelic and their musical legacies, reluctantly file this action in the face of multiple adverse claims from alleged successors in interest to those artists. Defendants continue to insist that plaintiffs' massively successful composition, Blurred Lines, copies 'their' compositions."
